EMBOSSING MACHINE.

Application filed December 20, 1922. Serial No. 607,961.

To all whom it may-concern:

Be it known that 1, WI LIAM J. PANNIER, Jr., a citlzen of the United Stateii residing at Pittsburgh, in the county or"v llegheny :3 and State of Pennsylvania, have inventedv certain new and useful Improvements in Embossing Machines, of which the following is a specification.

My invention consists of an improvement In in machines for embossing or marking cylindrical bodies, as cans or the like. It comprises a pair of oppositely rotating spindles provided with co-acting series of marking letters or characters, provision being made .5 for mounting such characters in proper arrangement, providing for easy and convenient changing of the characters and for fixedly holding them in position.

Also, in the construction of the spindles and their marking elements, whereby to effect periodical continuous pressure action on the blank and to also provide for intermittent separation of the co-acting surfaces by proper clearance spaces at corresponding sides of each spindle. The invention also embodies certain other features of construction and of advantages in operation, as shall be more fully hereinafter described.

In the drawing, showing one preferred embodiment of the invention,

Fig. 1 is a view of the embossing machine in side elevation;

Fig. 2 is a similar view in front elevation;

Fig. 3 is an enlarged sectional detail view on the line III-III of Fig. 1, showing the active embossing elements in open position;

Fig. 4 is a partial similar view, showing the coacting embossing members in closed or operative relation; -10 Fig. 5 is a plan view showing a flat degelopment of one of the embossing cyliners;

Fig. 6 is an enlarged cross sectional view on the line VIVI of Fig. 5; and

Fig. 7 is a detail in perspective of one of the marking units.

The machine as a whole comprises a double sided frame 2-2, suitably connect ed by transverse bolts 3 and having substantial pedestals 4 for mounting on a floor or other suitable base. The upper portions of frames 2 comprise housings 5 and 6 respectively, in which are mounted the journals of the cylindrical stem members 7-7. These are geared together by pinions 88,

' between the housing,

ing unit or type members 13-14 respectively, in male and female relationship, whereby to engage between them the cylindrical wall or shell member 15 of a can or other similar cylindrical sheet metal article.

The type members 18 and 14 are adapted to be inserted in rows between intervening holding strips 16, which in turn are fixedly secured to the spindle 7 by screws or bolts 17. In a similar manner, the terminal retaining members 18 of-the series are secured at each end of the several type spaces, by bolts 17, it being understood that one such member at one end may be fixed and the other removable for changing the type, as may be desired.

Between the outer surface of the spindle 7 and the inner bearing portions of the type members is a comparatively thin, partly cylindrical, bearing member 19 preferably of steel or other suitable metal. It is secured on the spindle in any suitable way and is adapted to provide a good bearing surface for the type and strip members, and serves to maintain their proper alinement and continuous circumferential relationship and action.

Each type member 13 or 14-. is provided along each of its side edges with a groove 20, adapted to interfit with a co-acting tongue 21 of the relatively stationary strip 16. By such construction, the entire series of type may he slid in between the adjacent holding members and will be fixedly retained in position during the operation of the machine, while at the same time being cap-able of easy removability or interchangeability.

In operation, the can, etc., to be operated upon is inserted between the spindles 7 when at their open position, as in Fig. 3, and as the type members on the embossing side come simultaneously opposite to each other,

they will grip the can and rotate it at the same speed, while impressing or embossing the letters, characters, Words, etc. in the sheet metal. The can in such manner is carried around until the opposite operative ends of the embossing members is reached, whereupon the spindles then assume the open inoperative position due to the clearanee provided, at which time the can may be removed and another can inserted.

The construction, operation and advantages of the invention will be readily understood and appreciated from the foregoing' description. It will also be understood that the machine may be variously changed and modified in detail construction, dimensions, or in various ways within the scope of the following claims.

\Vhat I claim is:

1. An embossing machine comprising a pair of coacting spindles, means for driving said spindles in synchronism, and cooperating embossing types in the tWo spindles, the type on each spindle being arranged in peripheral rows extending but partway around the respective spindles, the portionsof thespindles between the respective rows of type being disposed toward each other during each rotation of the spindles and providing a clearance space to permit of the insertion and removal of articles to be marked from between the spindles.

2. An embossing machine comprising a pair of coac-ting spindles, means for driving the spindles in synchronism, a plurality of spaced apart strips extending partway around the periphery of each roll, channels being formed between such spaced apart strips, marking devices in said channels, said strips and marking devices having coacting means for slidably retaining them in the channels, and a separate means movably secured at the end of each channel for closing the end thereof.

'3. An embossing machine comprising a pair of coacting spindles, means for driving the spindles in synchronism, a plurality of spaced apart strips extending partway around the periphery of each roll, and secured thereto, the ends of the strips being separated and being beveled, said strips providing channels on each spindle, and a series of marking members removably retained in the channels, the surfaces of the spindles across which the strips do not extend being positioned to come opposite each other upon each rotation of the spindle and provide a clearance space at that time between the spindles, and a beveled member at the end of each channel removably secured to the spindle for closing it.

In testimony whereof I hereunto affix my signature.
